About Flowmonster

Hidden beneath your ride lies a powerful creature destined to dominate. FlowMonster™ chambered mufflers create an aggressive exhaust note giving a powerful voice to your car/truck/SUV. FlowMonster mufflers are constructed of 16-gauge aluminized steel and are 100% MIG welded for maximum strength and durability. The chambered design cancels out unwanted frequencies with no packing producing an aggressive exhaust note that will not change with time. FlowMonster mufflers are coated with high heat-resistant silver paint for an aggressive look under your car.
